To aZZ'wwm may concer/n.:

Beit known that l, CHAnnns Parr, arcitla zen of the United States,v anda resident of Y New York, in the county of New York `and State of New`Yorkphavev invented certain new and usefulV Improvements in a Bunker, ofwhich the following is a full, clear, and exact specification. i

This invention relates to a class of structures adapted to be used for'storage of coal, grain, etc. j

My invention has for its obj ect' primarily to'provide a bunker designedto be employed for storing grain, coal and the like whereby largequantities of theproducts may be accumulated atfgiven-localities forgeneral distribution as well as being pro! tected during intervals fromexposure to weather, and .which -is constructed to withstand thev'strain V`ofheavy loads on its inf terior without its walls tending tobulge or give wayasis incident to bunkers-and storage Vstructures 44or"ordinary construction. The invention consistsessentia'llyo-a chamberhaving preferably reinforced concrete vor steelV walls formed of joinedcorner Sections and intermediate sections, the corner sections beingcurved throughout three- Vquadrants thereof and the intermediatesections being semi-cylindrically curved.V All of Vthe walls are-.madepreferably 01"' rein- Jforced concrete or steel so that when stressedVin tension under the weight of a load the pressure'at the marginal partsof the body of the contents of thercharnber will be dis- 'tributed inlateral directions as well as in outward directions relative to thecenter'of the body. The chamber is supported on a f trestle withpassageways for vehicles, and

v livery to the chutes.

thechamberhas a bottom composed of ad-l jacent downwardly taperedpockets each `with a gatecontrolled outlet leading into one of thepassageways to allow vehicles to berreadily loaded. Above the chambermay be spaced chutes one leading toward each Vof the taperedsections ofthe bottom, in

order tolperinit coalan'd Y'grain delivered to the chamber to be evenlydistributed therein, and above Vthechanaber is a conveyer which isoperable `forV carrying products pr de- VA further 4object of theinvention is to i.. provide a bunker of a simple, eiicient anddurablefconstruction which may be made in any suitable shape and size.

With these andiother objects in View the invention.

invention will be hereinafter more. particularly described withreference to the accompanying drawing forming a part of thisspecification in fwhich similar characters 01E-.reference indicatecorresponding partsin all the views, andfwill then be pointed out in theclaims at the end of the description.'

In the drawing,` Figure 1 is side clevation of one form of bunkerembodying my Fig, 2 is a sectional View, partly in detail, taken on theline 2 2 of Fig. l.

F ig. 3 is a front elevation of the bunker, and,

Fig. l is a `sectional view,partly in detail, taken on the line %4 of Fig. 2.

The bunker has a chamber 10 which may be' of any suitable size andshape, though the form of the chamber illustrated is approXima-telyrectangular to provide side walls 11, 12 and endwalls 13, le. The wallsare preferably erected of reinforced concrete or steel, and the wallsinclude four spaced corner sections 15, 16, 17, 13 each of which isfYcurved substantially three-quadrants thereof. Each of the Vside walls11, 12 may include three substantially semi-cylindrical sections, as19,20, 21, and each ot" the end walls 13, lll may consist of a singlesubstantially'semi-cylindrical section 22. The corner sections andintern'iediate sections are all joined together, Aas shown, so thattheir concavities form parts of the interior of the chamber. A v

The chamber lO is supported upon a trestle orfoundation, as 23, which iscornposed of a number of standards 24e arranged under the 4sections ci.the walls oi the chamber, and these standards are 'spaced apart toprovide passageways, as 25, which lead crosswise under spaced portionsof the chamber. In the passage-ways may be laid are .disposedso' thattheir apices are over` the tracks 27 ofthe passage-ways 25 of thetrestle 23. Inthe apexof each pocketv is a gate controlled outlet .29 ofany appropriate type to allow convenient opening and closing of theoutletsl when cars are i p maybe of any suitable construction, such`loaded xvith the contents of the bunker. On

thetop-of the chamber 10 is aroof 30 which as being of a form whereby issuperposed some distance above theopen top 'of the chamber, andleadinginto the roof maybe one -or more door controlled entrances, not

showm to allow coal, gra-in and other pro-V ducts to bedelivered tothechamber l0'.

,Interior-ly. ofthe roof 30`a-nd abovethe` open top of the chamberV 10is providedla trestle, as 31,' Which may -be supported :in

. any appropriate manner so that it ,extends preferably from end to endVof the roof 3) and'chamberl 10.V B.-rojecting in 'opposite lateraldirections from the trestle `81 are` a number oi. spaced pairs of chutes32 and 33, and these chutes may be of any suitable Widths and lengths asWell as being: dis posed from. the trestlewon' downwardA in clinesVtoward the tapered pockets 28 to permit coal, ygrain and the like to beldistributed evenly' to various parts of the interior of the chamber. y

In orderto convey products to the trestle 31 fordelivery tothe chutes32, 38 and fto the chamber l0 a conveyerd may be .provided onthe-trestle This conveyor may be of any ofthe :forms of Vappzmatus'commonly used for carrying coal or `grain from Y cars orother'vehicleslfat the base ot the Vbunker to the chutesxinV the roof ofthe bunker. .By providing fthe Walls -ofWth-e i bunker of the typesshown and described the Y In v the orgoing description,

pressure at the marginal edges of the Weight of the body Vor the`contents of the chamber l() will be distributed in lateral directionsas Well as Youtwardly because of admission of the contents into theconcavitics of theV sections ofthe Wall. The Walls of the `cham-- berwill thereby serve to withstand the strain of unusually vheavy loadsWithout tending to bulge or Vgive Way. Y

I have Vembodied' the preferred form of my inven# tion, but l do notwish to be understood as limiting myself thereto, as I amaware that Ymodifications may be made therein Without Mosca? departing from theprinciplefor sacrificing any of the advantagesv l ofthisginvention;therefore, I. reserveA to myself theright to make such changes asfairlyfall V.vithinth'e `scope' thereof.

Having thus 'described' myY invention, I
